Case Note & Summary
The case involved Swadeshi Polytex Ltd., which was engaged in manufacturing polyester fibre using ethylene glycol and DMT. The appellant sought a set off of excise duty paid on ethylene glycol under Notification No. 201/79. The Assistant Collector of Central Excise denied the claim, stating that no proforma credit was allowable for ethylene glycol used in methanol, a by-product, and other wastes. The Collector of Central Excise (Appeals) allowed the appeal, but the revenue contested this decision before the Tribunal, which ruled against the appellant. The core legal issue was whether the appellant was entitled to claim set off of duty on ethylene glycol used in the manufacture of polyester fibre. The appellant argued that all ethylene glycol was consumed in producing polyester fibre, while the revenue contended that the duty credit could not be claimed for non-excisable by-products. The Supreme Court analyzed the relevant notifications and trade notices, concluding that the Tribunal failed to properly interpret the exemption notification. The Court held that the interaction of ethylene glycol and DMT in producing polyester fibre inherently resulted in methanol, but this did not negate the entitlement to duty credit. The Court emphasized that the strict interpretation of exemption notifications should not prevent their intended benefits. Ultimately, the Supreme Court allowed the appeal, restoring the Collector's order that granted the set off of duty on ethylene glycol. No costs were awarded in the case.
Headnote
A) Central Excise Duty - Exemption Notification - Applicability of Notification No. 201/79 - The Court held that the clarification in the form of trade notice issued in respect of rule 56-A was applicable to notification No. 201/79. The Tribunal failed to interpret the exemption notification properly, which exempted excisable goods from duty equivalent to the duty paid on inputs, irrespective of by-products arising during manufacture. (Paras 272D-273A) B) Central Excise Duty - Proforma Credit - Entitlement to Credit - The Court clarified that the quantity of ethylene glycol required for producing polyester fibre is determined by chemical reaction, and the appellants were not engaged in producing methanol. The Tribunal erred in denying credit based on the by-product methanol. (Paras 273C-D) C) Central Excise Duty - Interpretation of Notifications - The Court emphasized that strict construction of exemption notifications should not frustrate their purpose. The Tribunal's interpretation was found to be incorrect as it did not consider the excisability of the final product, polyester fibre. (Paras 272E-F)
